Fix 2007/05/07 |
| 895 |
|
|
| 896 |
|
@ Support pathname subtraction. |
| 897 |
|
|
| 898 |
|
There was no way to exclude specific pathnames when granting |
| 899 |
|
permissions using wildcards. |
| 900 |
|
There would be a need to exclude specific files and directories. |
| 901 |
|
I introduced "\-" as subtraction operator. |
| 902 |
|
|
| 903 |
|
"A\-B" means "A" other than "B". |
| 904 |
|
"A\-B\-C" means "A" other than "B" and "C". |
| 905 |
|
"A\-B\-C\-D" means "A" other than "B" and "C" and "D". |
| 906 |
|
|
| 907 |
|
"A", "B", "C", "D" may contain wildcards. |
| 908 |
|
|
| 909 |
|
An example usage is "/home/\*/\*\-.ssh/\*", which means |
| 910 |
|
"/home/\*/\*/\*" other than "/home/\*/.ssh/\*". |
| 911 |
|
|
| 912 |
|
"A" should contain wildcards because subtraction from constants |
| 913 |
|
(e.g. "/usr\-usr/" or "/usr\-home/") is meaningless. |
| 914 |
|
|
| 915 |
|
Don't try "A\-B\+C" because "\+" is not addition operator. |

|
@ Fix autobind hook. |
| 920 |
|
|
| 921 |
|
The location to call SAKURA_MayAutobind() in net/ipv4/udp.c |
| 922 |
|
and net/ipv6/udp.c were wrong. |

@ Add a space in MakeMountOptions(). |

|
|

|
@ Fix ReadAddressGroupPolicy() bug. |
| 935 |
|
|
| 936 |
|
ReadAddressGroupPolicy() fails if both "path_group" and "address_group" are used |
| 937 |
|
because I forgot to set "head->read_var1 = NULL". |
| 938 |
|
|

Fix 2007/07/10 |
| 940 |
|
|
| 941 |
|
@ Add compat_sys_stime() hook. |
| 942 |
|
|
| 943 |
|
Some of 64bit kernels support compat_sys_stime() |
| 944 |
|
but permission check was missing. |
| 945 |
|
|
| 946 |
|
Version 1.4.2 2007/07/13 Bug fix release. |
| 947 |
|
|
| 948 |
|
Fix 2007/08/06 |
| 949 |
|
|
| 950 |
|
@ Remove mount-flags manipulation. |
| 951 |
|
|
| 952 |
|
Until now, administrator is permitted to turn on/off specific mount options |
| 953 |
|
regardless of mount options passed to kernel. |
| 954 |
|
I removed this feature because "exact option matching" sounds better than |
| 955 |
|
"automatic option enabler/disabler". |
| 956 |
|
|
| 957 |
|
@ Remove /proc/ccs/info/mapping . |
| 958 |
|
|
| 959 |
|
I removed /proc/ccs/info/mapping because nobody seems to use this feature. |
| 960 |
|
|
| 961 |
|
@ Call external policy loader automatically. |
| 962 |
|
|
| 963 |
|
Until now, users had to add init=/.init parameter to load policy |
| 964 |
|
before /sbin/init starts. |
| 965 |
|
I inserted call_usermodehelper() to call external policy loader when |
| 966 |
|
execve("/sbin/init") is requested and external policy loader exists. |
| 967 |
|
|
| 968 |
|
This change will remove init=/.init parameter from most environment, |
| 969 |
|
although call_usermodehelper() can't handle interactive operations. |
| 970 |
|
|
| 971 |
|
@ Move external policy loader from /.init to /sbin/ccs-init . |
| 972 |
|
|
| 973 |
|
Installing programs in / directory is not good for packaging. |
| 974 |
|
|
| 975 |
|
Fix 2007/08/13 |
| 976 |
|
|
| 977 |
|
@ Update external policy loader. |
| 978 |
|
|
| 979 |
|
It turned out that /sbin/ccs-init invoked via call_usermodehelper() |
| 980 |
|
can handle interactive operations by opening /dev/console . |
| 981 |
|
Now, there is no difference between init=/sbin/ccs-init and |
| 982 |
|
call_usermodehelper("/sbin/ccs-init"), and users no longer need to |
| 983 |
|
add init=/sbin/ccs-init parameter to load policy before /sbin/init starts. |
| 984 |
|
|
| 985 |
|
Fix 2007/08/14 |
| 986 |
|
|
| 987 |
|
@ Update recvmsg() hooks. |
| 988 |
|
|
| 989 |
|
Until now, it was impossible to apply network access control for |
| 990 |
|
incoming UDP and RAW packets if they are brought to userland using |
| 991 |
|
read() or recvmsg() with NULL address because address buffer is NULL. |
| 992 |
|
I moved hooks from sock_recvmsg() to skb_recv_datagram() so that |
| 993 |
|
network access control for incoming UDP and RAW packets always work. |
| 994 |
|
|
| 995 |
|
Fix 2007/08/16 |
| 996 |
|
|
| 997 |
|
@ Return appropriate error code for CheckMountPermission(). |
| 998 |
|
|
| 999 |
|
I was returning -EPERM if something is wrong with CheckMountPermission(). |
| 1000 |
|
But SELinux determines whether selinuxfs is supported by kernel |
| 1001 |
|
based on whether error code is -ENODEV or not. |
| 1002 |
|
So I stopped returning -EPERM unconditionally. |
| 1003 |
|
|
| 1004 |
|
Fix 2007/08/17 |
| 1005 |
|
|
| 1006 |
|
@ Remove initializer directive. |
| 1007 |
|
|
| 1008 |
|
Use "initialize_domain" instrad of "initializer". |
